Benefits of technology

[0007] It is an object of the present invention to provide a smokeable tobacco substitute that has an increased fill value.
[0008] It is also an object of the present invention to provide a smokeable filler material having improved tobacco taste and flavor characteristics with minimal Hoffman Analyte deliveries.
[0009] It is a further object of the invention to provide a smokeable filler material having an improved burn rate, smoke delivery, and propensity to resist extinguishing.
[0010] The present invention meets these objectives and provides additional benefits to the smoking article by replacing the large natural granular chalk found in the prior art fillers with precipitated and refined chalk having a smaller particle size and replacing at least a portion of the chalk with a less dense filler having a cellulose containing material.

Problems solved by technology

However, even in this form, the unacceptable taste of these filler materials is noticeable and detracts from smoking pleasure.
Additionally, many of the non-tobacco filler materials have a low fill value which results in a heavy smoking article with a low burn rate, low smoke delivery, and high propensity to extinguish.

[0030] Several embodiments of the present invention were made according to the processes described herein and the fill value of these embodiments were measured and compared to the fill value of the tobacco filler material found in the prior art. The fill value was determined by placing a 10 g to 20 g sample of filler material into a densimeter and compressing the filler with a 2 kg piston for 30 seconds. The height of the piston in the densimeter as well as the moisture content of the samples were measured. The fill value of the samples were calculated according to the following formulas:

UFV(cc / g)=(2.78×H) / W

CFV(cc / g)=UFV+(−0.76×(T−M)+0.01×(T2−M2)

Wherein UFV in an uncorrected fill value, H is the final compressed height of the piston in the densimeter, W is the weight of the sample in grams, CFV is the corrected fill value, M is the percent moisture content of the sample, and T is a target moisture of 14%.

Abstract

The invention relates to a smokeable filler material having an increased fill value and processes for making the smokeable filler. The smokeable filler has a fill value of at least 5 cc / g and comprises a cellulose material, a humectant, an inert filler, a binder, and optionally a tobacco containing material.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Not applicable. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not applicable. FIELD OF INVENTION [0003] This invention relates to smokeable filler material for smoking articles, and in particular to a smokeable filler material for a smoking article where the filler has an increased fill value and closely exhibits properties of tobacco in a smoking article while reducing the Hoffman Analytes associated with tobacco. BACKGROUND OF THE INVENTION [0004] In the many efforts which have been made to provide alternative smokeable filler materials with reduced Hoffman Analyte delivery very few, if any, have been found which produce a smoke taste and flavor which is acceptable to smokers of conventional tobacco containing products. Many of these fillers contain mostly, if not entirely, chalk or other inert fillers. Therefore, most alternative filler materials have been used in conjunction with cut tobacco leaf or tobacco-...
